Hello everyone. I am trying to fix this Galaxy S6. Mangaged to open it all and removed the battery. I assumed it was the battery because of how the phone died. I dont have a replacement battery tho, because i dont want to spend money on something that might not be the problem. My question is, can it still be powered if I remove the battery and try to turn it on directly connected to micro usb power?

In that model, the battery is not designed to be removable, however, if you did manage to remove it, it will still power up if plugged in to usb port as if you were charging it.

I would say that this depends on the phone. With an adapter. Most phones now use USB to charge and it will also run the phone with or without the battery.

It will turn on charging it but it will have a bootloop, it will show the name screen and then It will turn off. You can plug to a charger and turn it on in download mode, there it will stay on but you won’t access to the system
